Correct Answer - Option 1 : (Newton) . (Meter)
Explanation:
Work is said to be done by a force when it moves its point of application through a distance.
Work done = Force × Distance moved
SI unit of work is joule. 1 J = 1 N.m
Joule: When a force of 1 Newton acting on a body through a distance of 1m
Power is defined as the rate of doing work.
P = W/t (J/s = Watt)
Joule = Watt × second
